I figured you would have some info on this Kent. 

I saw something on TV (I was forced to watch, I was at a friends house) and it linked Mad Cow to a dementia often seen in folks who practice cannibalism.  They said it's from eating the brains of humans.  Then they talked about how rendering plants cook down all the "non edibles" of cattle and then make it into this Cow-Chow and feed it back to them and that was how it all started. 

But, of course, I don't believe it.  I think the Cows are eating people's heads.  That's the only LOGICAL conclusion. :) The only question is...are the heads ON the human's bodies at the time or are they having them SHIPPED in.

They look all calm and serene but I know...

Sorry for bein' silly.
